Enter the chemical formula of a compound to calculate its molar mass and elemental composition:
Instructions to calculate molar mass (molecular weight) of a chemical compound:
To calculate molar mass of a chemical compound, please enter its chemical formula and click 'Calculate'.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
Calculate the dilution required to prepare a stock solution
The Adooq dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.
The dilution calculator equation
The Adooq dilution calculator is based on the following equation:
Concentration(start) x Volume(start) = Concentration(final) x Volume(final)
This equation is commonly abbreviated as: C1V1 = C2V2
An example of a dilution calculation using the Adooq dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
Calculate the mass, volume or concentration required for a solution
The Adooq molarity calculator is a useful tool which allows you to calculate the:
mass of a compound required to prepare a solution of known volume and concentration
volume of solution required to dissolve a compound of known mass to a desired concentration
concentration of a solution resulting from a known mass of compound in a specific volume
The molarity calculator equation
The Adooq molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the Adooq molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
